The success rate of two groups were 100%, and the mean degree of
splenic embolism by SPSE was 82.4% (75%-90%), which close to the
extent of expected embolism. The improvement of hemolysis in patients
after SPSE was not different from that after total splenectomy, and the
effect can be maintained for a long time. The average hemoglobin value
increased significantly from 6.97g/dL before SPSE to 12.2g/dL after SPSE
(P < 0.001). SPSE was performed without any serious
complications. All children suffered mild to moderate postembolization
syndrome including pain, fever and vomiting, which could easily be
controlled with appropriate supportive therapy.
